11 Claims.

This invention relates to sliders for separable fastener stringers. Still more particularly, the invention deals with a lock slider construction having a swivel pull for actuating the lock element of the slider, and means suitable for detachabiy mounting ornamental or characterizing members therewith. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. l is a sectional view through a slider made according to my invention, showing the lock element of the slider in operative position in full lines, and in inoperative position in dot-dash lines.

Fig. 2 is a side view of the structure shown in Fig. i., with parts in a different position; and

Fig. 3 is an exploded perspective view showing the several parts of the slider detached.

In lock sliders of the kind under consideration, it has been customary to couple the pull on a xed pivot to swing in the path of movement of the slider along the stringers and in some instances,-the lock element of the slider has formed an integral part of the pull.

With my present slider construction, the pull has a rotatable mounting on the slider or on a turret portion of the lock element of the slider so that the chain or other ingerpiece portion of the pull can be swung to either end portion of the slider in operation thereof along the stringers. The lock element has a pivotal mounting on the slider with tensional means normally supporting the lock pin or finger of the element in operative position.

In the drawing, I I) represents a slider body having top and bottom walls II and I2 joined centrally at one end by a connectingweb I3 having a recess It in the upper surface of the top wall Ii. The slider is generally of the contour illustrated in Fig. 3, and the top and bottom walls II and i2 have inwardly extending side flanges I5 and IS respectively, defining the channel Il of the slider. The top wall II of the slider has an elongated aperture IB opening into the channel Il and centrally of the slider is an upstanding pivot pin Iii, preferably made integral with the wall II, the pin having a reduced upper end 20 which forms a shoulder, as at ZI.

Considering Fig. 3 of the drawing, the slider comprises other parts which will be generally classified as follows. At 22 is shown a coil spring which seats and operates in the recess I4, and at 23 is shown a washer seated on the shoulder 2l of the reduced portion 2li and held thereon by riveting over the top of the reduced portion, as seen at 24, note Fig. 1. The Washer 23 holds a lock element 25 in position upon the post I9 or against displacement therefrom. The element 25 has a tubular turret portion 26 grooved, as seen at 2l, to receive a split ring 28, the latter retaining a pull 29 against displacement from the lock element 25 while permitting the pull to rotate freely around the turret 26. The upper or open end of the turret preferably has a closure applied to it, and this closure may conveniently serve as an anchor for a detachable ornament. As illustrated, the turret closure, marked 30, takes the form of a socket member of any desired form, similar to conventional socket members of snap fasteners. At 3| is shown a characterizing member having centrally of its lower face a spring studded part 32 for snap engagement with the socket S in detachably coupling the member 3| therewith.

Returning now to the lock element 25, this element has at the periphery thereof a down-- wardly directed pin or finger 33 which operates in the aperture I8 in engaging the scoops of stringers to lock the slider against movement along stringers in the direction of the arrow 34, note Fig. 1.

In Fig. 1 of the drawing I have diagrammatically illustrated in dot-dash lines at 35, scoops of a Stringer 36. As fasteners of the kind under consideration are well known in the art, it is not deemed necessary to show the assemblage on stringers.

The lock' element 25 has within the turret 26 a large recess or socket 3l in which the washer 23 and pin end 2li-24 are arranged, as well as the socket 3U, the socket 38 being held in position by seating upon a shoulder 38 in the recess 3l and by peepingl or riveting over the upper end of the turret, as seen at 39 in Fig. l of the drawing. The lock element 25 is so coupled to post I9 that it is free to seesaw back and forth between the full and dotted line positions indicated in Fig. 1. In the construction illustrated, the lower portion of the lock element 25 has centrally of the recess 37 an oversize and preferably conical aperture 40, note Fig. 1, and on opposed sides of the aperture All, the lock element 25 has rounded projections 4I adapted to seat upon the wall I I to facilitate pivotal or rocking movement of the lock element, as indicated in :full and dotted lines in Fig. 1, the conical aperture 40 permitting the swinging movement of the lock element, as will be apparent. The pull 29 has an extending part 42 apertured as seen at 43, for the reception of a chain or other ngerpiece portion, as indicated at 44 in Fig. 1 of the drawing.

The upper surface of the turret 26 has a key recess 45 adapted to receive a key element 46 on the member 3l to retain said member in predetermined position upon the turret, particular'ly when the member 3i has, as a characterization, an initial as at 47 to maintain this initial in proper alignment upon the slider-at vall times.

Considering Fig. 1 of the drawing, it will appear that the spring 22 bears upon the lower surface of the lock element and-serves to normally maintain the pin or lock part 33 in operative position. Considering Fig. 3 of the drawing, it will appear that the pull 29 is substantially in the form of a ring having a large aperture 48, which nts freely around the turret to -provide for the swinging or rotary movement of the pull on the turret.

By providing the snap fastener socket or vsimilar attaching member in the turret portion of the lock element, characterizing members having stud parts or similar' couplings may be detachably mounted in connection with the slider. This is extremely desirable from a sales standpoint, where numerous characterizing members may be employed and attached to the slider upon the sale of the fastener or the garment to which the fastener is attached. Aside from employing ornamental characterized members, the members may simply have one or more initials to personalize the fastener part, garment or article to which the fastener' is attached. The latter adaptation of the invention is particularlyr desirable when fasteners are employed in conjunction. with luggage, briefcases and the like, and on v `ious types and kinds of wearing apparel, including pocketbooks and cases of various kinds and classes.

it will also be understood that my invention lends itself to the application of symbols or emblems identifying clubs, fraternal organizations and the like. Most of the parts of the complete fastener' can be formed as die castings in metal or plastics, or combinations of metal and plastic, thereby materially simplifying the cost of producing the complete slider. It is here also well to state that proportional sizes, as illustratedin the accompanying drawing, are exaggerated for sake of clarity in the illustration.

It will be app-arent that in operating the slider along the stringers to couple the stringers, that is to say, in movement in the direction of the arrow 34, the ngerpiece or pull 29 raises the lock element to withdraw the finger 33 from the channel Il. However, in movement of the slider in the opposite direction to uncouple the stringers, the finger 33 ratchets over the scoops against the action of the spring 22.
